search_exact: Search for an Exact Match

In patelm9/metaorite: metaorite Package

Description

These functions help search for mappings between an a concept and a Metathesaurus identifier in the MRCONSO Table. All queries are cached using the R.cache package for quicker retrieval of the more computationally expensive searches.

Usage

search_exact(
  conn,
  concept,
  schema = "mth",
  match_case = TRUE,
  cache_only = FALSE,
  skip_cache = FALSE,
  override_cache = FALSE
)

Arguments

conn	Postgres connection
concept	Concept to be searched
schema	Metathesaurus schema
match_case	If TRUE, both the MRCONSO STR column and the 'concept' argument are converted to lowercase.
cache_only	If TRUE, only the cache is loaded and database querying is skipped. If a cache did not exist for the query, a NULL will be returned.
skip_cache	If TRUE, the cache is skipped altogether. The database is directly queried and the resultset is not cached.
override_cache	If TRUE, the cache is not loaded, the database is directly queried and the resultset is cached, overwriting any existing cache that may have been present.

Value

Dataframe of 0 or more rows of all the fields in the MRCONSO Table.
